rApplication led December 17, 1906. Serial No. 348,108.

citizen of the United States,`and resident of.

the borough of Manhattan, city,.county, and State of New York, have invented certain new and useful Improvements in Gas-Gem erators, of Which the following is a specification, accompanied by drawings.`

This invention relates to gasgenerators, more articularly tov generators of the type in which the solid gas generating material is fed to the liquid, and Vthe objects of the invention are generally to improve upon the construction and operation of such machines.

Another object of the invention is to prevent the accumulation of the gas` generating material at any one place in a generator tank.

Further objects of the invention are to improve the circulation in the tank, and thereby facilitate the removal of the residuum.

Further objects of the invention will hereinafter appear and to these ends the invention consists of` a gas generator for carrying out the above objects embodying the features of construction, combinations of elements, and arrangement of parts having the general mode of operation substantially as herein:

after fully described and claimed; inl this specification and shown in the accompanying drawings, in which,- v

Figure -1 is a front elevation of apparatus embodying the invention; Fig. 2 is a perspec tive side elevation of the apparatus; Fi 3 is a horizontal sectional view on the line 3 3 of Fig. l Fig. 4 is a vertical sectional side elevation on the broken line '4-4 lof Fig. 5; Fig. 5 is a partial top plan view of the apparatus; Fig. 6 is an en arged detail vertical sectional view taken through the central shaft of the apparatus; Fig. 7 is a detail top plan view of a portion of Fig. 6.

Referring to the drawings', A represents the generator tank and B is the hopper carried upon the -neck C supported from the top of the tank A. Suitable means areprovided for feeding` the gas generating. material, as

for instance the endless conveyer in the form and F, and driven by the sprocket wheel G from a suitable source of power.` lUnder-` neath the upper side of the chain is a trough or plate II, while the shield I extendsdownwardly underneath the chain.

In this instancev a suitable hydraulic motor in the form of animpulse wheel within the casing J is connected to operate the chain D as by means of the Worm K, Wheel L and sprocket chain O. The intake for the impulse motor is represented at I), while Q represents the outlet pipe for the tail Water,

shown in this instance as communicating `with the lower portion of the generator tank A, therebysupplying the tail water to the generator tank. The gas outlet pipe R communicates with the upper portion of the generator tank by means of the dome S, and leads to a suitable hydraulic seal T, from whence the gas is supplied for use. f

Within the generator tank A is provided a vertical partition a, preferably cylindrical and su ported as by means of the arms b from tllie central tubular shaft or sleeve c, the lower end of which is supported in a step bearing d on the slanting bottom e of the tank, the upper end extending through a stuffing boXf, and being provided with a Worm wheel g loose thereon, meshing with a worm h adapted to be driven by the Y vfast to the tubular shaft and pivoted on the worm wheel g and 7c is a pawl 0 adapted to engage the teeth of the ratchet'wheel y', and thereby impart rotation from the worm .wheel g through the -ratchet wheelY to the shaft c.

Extending through the tubular shaft c is a rod pprovided at its upper end with a handle g .for raising and-lowering the rod. Adjacent the handle g are the lugs r adapted to be seated inthe slots s in the upper end of the tubular shaft c. Between the lugs r i and the top of the tubular shaft is arranged a loose collar s having slots r', through which the lugs r may be lowered when the slots andthe collar are rotated to register with said lugs 1. y Ihen the shaft p is raised the collar s may be rotated to bring the ,y `slotsrr out of register with the lugs r, as of a linked chain I) carried bythe rollers E shown in Fig. 7, thereby supporting the the lugs t at the lower end of the shaft p out `of engagement with the stirrer blades c.

Transversely extending lugs or pins t are connected to thelower end of the rod p and extend through slots u in thelower end of the tubular shaft c. Loosely mounted upon the lower end of the shaft c are the stirrer blades o provided with slots in the collar w, into which the lugs t Aare adapted to be seated when the rod p is lowered by means of the handle g, thereby connecting the rod p to rotate with the shaft c and imparting the rotation to the stirrer blades o.

Loosely mounted upon the upper end of the tubular shaft c above the ratchet wheel j is a collar V provided with a hand operating lever W and an arm x, provided with a pawl y adapted to engage the teeth of the ratchet wheel so that by reciprocating the hand operating lever l the ratchet wheel j may be rotated, thereby rotating the shaft c and vertical partition 0lv by hand when desired. At the same time if desired rotation may be manually imparted to the stirrer blades e.

An annular screen 2 is suitably supported around the outside of the vertical partition a in any suitable manner as by means of the arms or struts 3, and preferably the top of the partition a is adapted to be below the normal level of the water in the tank. A cylindrical screen 4 is shown arranged eX- tending above the top of the partition a and reaching above the normal water level.

It will be observed that the neck C of the feeding hopper B is located at one side of the top of the tank so that the gas generating material is fed on tothe screen 2 at one side of the partition a. rlhe continuous rotation of the partition a and screen 2 during the feeding prevents the material from accumulating` in any one place en the screen and insures the distribution of the gas generating material over a considerable area in the tank, thus inducing a circulation from all sides of the partition a upwardly over the top of the partition through the screen 4 and downwardly within the partition a as indicated by the arrows in Fig. l.

5 represents hand hole on the side of the tank A for cleaning purposes, and an aperture 6 is provided in the lower portion of the side of tlee tank communicating with an outer chamber 7, in which the residuum overiiow pipe 8 is provided. TVents 9 are provided in the walls of the tank A above the normal water level between the gas generating chamber and the chamber 7, so that the water will stand at the same level in each chamber. As shown, the residuum overflow ipe 8 is in the form of a U, and the water evel extends substantially to the upper edge of the pipe in the chamber 7. The outer leg of the U-shaped pipe 8 extends outside of the chamber 7 and is provided with the downtake pipe 1.0, which is also provided with a branch l1 communicating with the lower end of the chamber 7 at the aperture l2, and

also provided with a valve .13 to enable the heavy residuum which collects on the bottom of the tank to be drawn ofl at intervals. A

pipe 11 is also provided with a sludge cock lll.

rlhe revolving screen or support within the tank A acts as a conveyor to convey the gas generating material away from the point al which it is deposited within the tank. The abject in doing this is to prevent the accumulation of material at any one place, which would interfere with the relatively slow reaction, because the material would pile up faster than it could be reacted upon. `\Vhen the material is allowed to pile up the particles in the interior of the pil\I are covered in and the liq'uid is prevented from reaching them, thereby interfering with the completeness of the reaction. With the ordinary materials for generating gas the material is all used up by the time that the point on the screen upon which the material has been dropped has made a complete revolution and again arrived at the place at which the malerial is falling through the water from the hopper. The screen therefore acts as a conveyer to convey the material away from the point at which it was iirst received.

An endless traveling lsubmerged conveyor' of any suitable type, as for instance slats connected to sprocket chains, may he arranged in the generator tank on suitable rollers and this endless conveyor may he onnccted to be driven in any suitable manner from the impulse wheel in the casino; (l. 'l`hc endless conveyer should be so arrangedy that the material i'alls upon one end el the saine and is continuously carried through the liquid in the tank and deposited at a point remote from the point at which it received.

bviously somo features ol' this invention may be used. without others and the invention may be embodied in widely varying forms.

Therefore, without limitinfi the invention to the devices shown and described, and without enumerating equivalents, l claim and desire to obtain by Letters Patent the. following i.
